In a recent issue of 'Agenda' Magazine Henry comments on Part IIIA of the Australian Trade Practices Act.

Abstract:
Part IIIA of the Australian Trade Practices Act defines circumstances in which a facility owner may be required to provide a third party with use of its facility. This paper examines what Part IIIA might be doing from an economic perspective and criticises ‘monopoly leveraging’ arguments for third-party access. It argues that the transactions costs of access are potentially significant, and can exceed any efficiency gains third-party access permits. These contentions are corroborated by reference to the long-running dispute between the Fortescue Metals Group and BHP Billiton Iron Ore over access to rail track in the Pilbara region of Western Australia.
